1 SUMMARY OF CONSTITUENTS OF POTENTIAL CONCERN (COPCs) TRANSPORT
PATHWAYS TO THE CREEK
The current understanding of the transport mechanisms of contaminants from the upland
portions of the Levco Metals Property site (site) to Newtown Creek is summarized in this
section and Table 1, and is supported in the following sections.
Overland Transport
The site is located approximately 1.3 miles from the Dutch Kills waterway (a tributary of
Newtown Creek) with several buildings and thoroughfares between the site and the
waterway. The site is 1.3 miles from Newtown Creek and associated waterways. This is not
a complete current or historical pathway.
Bank Erosion
The site is not adjacent to Newtown Creek or associated waterways. This is not a complete
current or historical pathway.
Groundwater
The site is 1.3 miles from Newtown Creek and associated waterways. According to the 1995
Proposed Remedial Action Plan, there is a groundwater plume on the central portion of the
Draft Upland Site Summary Report

site between 36th and 37th Street (NYSDEC 1995). Groundwater at the site flows to the
southwest toward the East River. This is not a complete current or historical pathway.
Overwater Activities
The site is not adjacent to Newtown Creek or associated waterways. Information regarding
overwater activities was not identified in documents available for review. This is not a
complete current or historical pathway.
Stormwater/Wastewater Systems
This site is within the Bowery Bay WPCP sewershed (NYCDEP 2007). Information
regarding on-site stormwater and wastewater infrastructure and management were not
identified in documents available for review. There is insufficient evidence to make a
current or historical pathway determination for direct discharge of stormwater and
wastewater or discharge to sewer/ CSO.
Air Releases
An air sparging/soil vapor extraction system (AS/SVE) system installed on the site in 2003 to
address elevated levels of VOCs found in soil and groundwater at the site (Gannett Fleming
2006). In 2010, the AS/SVE system was deemed ineffective and was discontinued (Cozzy
2010). Additional information regarding air emissions from the site was not identified in
documents available for review. There is insufficient evidence to make a current or
historical pathway determination.
2 PROJECT STATUS
Based on the presence of elevated levels of 1,1,2-trichloroethylene (TCE) groundwater
underlying the site, the site is listed on the New York State Environmental Site Remediation
Database as a “Class A” VCP site (i.e., a non-registry site in any remedial program where
work is underway and not yet complete). The site was listed on the New York State Registry
of Inactive Hazardous Waste (HW) Sites (HW No. 2-41-009) as a Class 2 Site in November
1989 but is now delisted from the Registry. A summary of investigation and remedial
activities at the site is provided in the following table:

4 PROPERTY DESCRIPTION
The property occupies approximately 0.5-acre located 1.3 miles from Newtown Creek and
associated waterways. The site is approximate 40 feet above mean sea level. The site and
surrounding are flat as shown on Figure 1. The entire site is paved. Site maps are presented
at Attachments 1 and 2. The property is bounded to the north and south by commercial
buildings, to the east by residential dwellings, and to the west, a film and recording studio,
Kaufman Astoria Studios. The area is zoned as a Manufacturing District, M1-5 (New York
City Department of Planning 2011a). M1 districts are designated for areas with a significant
number of residential buildings (NYCDCP 2011b).
5 CURRENT SITE USE
The site is currently paved with an asphalt surface and used as a parking lot for adjacent
tenants. No structures currently exist on the property. Plans for construction of a new
building at the site are pending (D&B 2010).
6 SITE USE HISTORY
In 1917, the New York Telephone Company owned the property with two storage
warehouses: one on Blackwell Street (currently 36th Street) and one on Pomeroy Street
(currently 37th Street). Available records did not indicate what was stored at these locations.
The center of the property was a paved court (Sanborn 1917).

By 1943, The East River Gas Company Customer Service Department occupied the site. Two
gas tanks were close to 7th Avenue (formerly Blackwell Street and currently 36th Street) and
two warehouses were still in the same locations (Sanborn1943).
Around 1950, Levco Metal Finishers, Inc. (Levco) began manufacturing metal novelties on
the site. They conducted plating and casting of white metal for lamps and novelty trade
(Chamber of Commerce 1950). Years later, Levco described their business as sulfuric
anodizing, chromic, hard coating, spraying, polishing, and plating (Chamber of Commerce
1969). By 1983, Levco occupied a 22,500 square foot facility for spraying, anodizing, and
plating metals (State of New York 1983). Levco ceased operations in 1990. The one story
structure was demolished (NYSDEC 2003b).
7 CURRENT AND HISTORICAL AREAS OF CONCERN AND COPCS
The current understanding of the historical and current potential upland and overwater areas
of concern at the site is summarized in Table 1. The following sections provide brief
discussion of the potential sources and COPCs at the site requiring additional discussion.
Areas of concern at the site include two storage buildings, two gas tanks, products used in
metal finishing practices and operations (including sulfuric anodizing, chromic, hard coating,
spraying, polishing and plating), equipment used in metal finishing practices and operations
(including a concrete sump area), and one aboveground and one underground storage tank
(AST and UST). The COPCs associated with these areas include VOCs, chlorinated VOCs,
organic solvents, semi-volatile organic compounds (SVOCs), metals, petroleum hydrocarbons
and polycyclic aromatic hydrocarbons (PAHs).
7.1
Uplands
Historic sources of COPCs at the site are identified to originate from metal finishing
operations using hazardous materials including inorganic acids and their salts, and organic
solvents. Various site investigations conducted at the site have implemented soil borings,
monitoring wells, and various soil vapor monitoring and extraction wells, or a combination
thereof (see Attachments 1, 2 and 3). Remedial measures have revealed the presence of
chlorinated hydrocarbons and heavy metals in soil and groundwater. COPCs associated with
Newtown Creek RI/FS

operations at the site include cis-1,2 –dichloroethane (cis-1,2-DCE), 1,1-dichloroethene (1,1DCE), 1,1-dichloroethane (1,1-DCA), 1,1,1-trichloroethane (1,1,1-TCA), TCE, cadmium,
chromium, lead, and selenium (NYSDEC 2003a).
The primary area of concern at the site includes the former sump area located in the
southeastern portion of the former metal finishing building (see Attachment 3). Previous
investigations revealed a VOC plume believed to originate from past discharges of liquid
chemicals and waste into the sump (Levco Woodwork Joint Venture 2002). The VOC plume
included elevated levels of TCE as well as cadmium and chromium contamination. These
chemicals were present in the groundwater and were found to be moving off-site via
groundwater flow (NYSDEC 1996). An Internal Remedial Measure (IRM) was implemented
in 1993 to remove impacted material from the sump (Levco Woodwork Joint Venture 2002).
The former one-story brick building used for metal finishing practices was constructed on a
slab of concrete except for a 500 square foot basement at the northwestern end of the
building. The basement included a boiler and aboveground storage tank (AST) used to store
fuel oil. When the building was decommissioned in 1991, approximately 36,288 gallons of
hazardous waste liquids, 38 lab-packs of small containers holding hazardous waste (less than
one gallon each), and 90 cubic yards of hazardous waste solids (i.e., woodchips, wood, and
debris) were all manifested and removed (NYSDEC 1996; Levco Woodwork Joint Venture
2002). Additionally, asbestos was identified in the boiler room prior to decommissioning of
the building (Geraghty & Miller 1995).
The site is a registered petroleum bulk storage (PBS) facility (PBS No. 2-090360; NYSDEC
2012). One 5,000-gallon UST is identified under PBS No. 2-090360 as in service for No. 2
fuel oil storage.
The site has historically been classified a Resource Conservation and Recovery Act (RCRA)
large quantity generator (LQG) and non-generator in 1987 and 1990, and 1999 and 2006,
respectively (EDR 2010). The site was most recently classified a non-generator; however,
available documents have not been updated since 2007 (EDR 2010). The site has on file…

8 PHYSICAL SITE SETTING
8.1
Geology
In general, the geologic setting of Newtown Creek area consists of Quaternary glacial
deposits overlying Paleozoic gneiss and schist bedrock (Misut and Monti 1999). The contact
between the glacial deposits and bedrock slopes rather steeply to the southeast, ranging in
depth from less than 50 feet below ground surface (bgs) near the mouth of Newtown Creek
to over 200 feet bgs at the eastern portions of the historical data review area. The near
surface geology is of most interest relative to potential groundwater transport pathways from
upland sites to the creek. In most areas, a heterogeneous anthropogenic fill unit of variable
thickness (generally less than 20 feet thick) immediately underlies the surface. Beneath the
fill in most areas are complex upper glacial deposits of Late Pleistocene age consisting of
ablation till, outwash, and glaciolacustrine sediments. In some areas near Newtown Creek, a
shell-bearing gray silt unit is present beneath the fill; this silt may represent post-glacial
intertidal sediments deposited in wetlands adjacent to the creek prior to filling in the 1800s.
An extensive sequence of regionally significant glacial units underlies the upper glacial
deposits in areas where bedrock is deeper (Misut and Monti 1999).

Geologic conditions at the site have been characterized to depths 50 feet bgs. A 2002
investigation report described observed site lithology from the ground surface downward as
follows (Levco Woodwork Joint Venture 2002):
•
Fill material from 0 to 4 feet bgs
•
Medium to fine sand with some silty material from 4 to 20 feet bgs
•
Coarse sand with traces of gravel from 20 to 50 feet bgs
•
Bedrock 50 feet bgs
A total of 16 soil borings (12 were converted to monitoring wells) and 19 monitoring wells
were installed to investigate the subsurface of the site. Attachments 2 and 3 present the soil
boring and monitoring well locations at the site. Attachments 4, 5, and 6 show
hydrogeological cross sections that run from east to west through the site.
8.2
Hydrogeology
Hydrogeologic conditions at the site have been characterized for the unconfined
groundwater unit at an average depth of 16 feet bgs (Levco Woodwork Joint Venture 2002).
Generally shallow unconfined groundwater flow at the site is to the southwest toward the
East River.
Groundwater elevations at the site have been measured in a network of monitoring wells
using depth to water field measurements in relation to a known surveyed reference point
(e.g., top of casing). The groundwater zone is dominated by a layer of medium to fine sand
with some silty material to approximately 20 feet bgs and coarse sand with traces of gravel
below 20 feet bgs. The groundwater beneath the site is not a current source of drinking
water in the Astoria section of Queens (Levco Woodwork Joint Venture 2002). The
hydraulic gradient of the water table is relatively flat (approximately 3.125 x 10-4 feet per
foot). Measurements from groundwater monitoring well clusters indicate a negligible
vertical head gradient in the upper 25 feet of the saturated zone (Levco Woodwork Joint
Venture 2002).
Monitoring well locations are shown in Attachments 1, 2, and 4. Attachment 7 shows waterlevel elevations and groundwater flow directions from a November 22, 1994 investigation.

Soil Investigations
Multiple soil investigations at the site were conducted between 1987 and 1994. In 1987, soil
samples were collected from four boring locations to characterize soil lithology. In April
1990, a Consent Order was executed between New York State Department of Environmental
Conservation (NYSDEC) and the potentially responsible parties (PRPs) named as the LevcoWoodwork Joint Venture, Levco Associates, and Woodwork Display Astoria Investors,
requiring the PRPs to implement a Phase II Investigation Program. The Phase II
Investigation, conducted in 1992, was intended to delineate the extent of VOCs present in
groundwater. The investigation included 13 soil borings, 9 of which were converted to
monitoring wells, up to 48 feet bgs. The highest concentrations of VOCs were identified to
exist in soil and groundwater samples closest to the main sump at the northwestern-most
corner of the former one-story building (Levco Woodwork Joint Venture 2002). Nonaqueous phase liquids (NAPLs) were not detected in the soil or groundwater samples
collected at the site. The absence of NAPL is further supported by relatively low
concentrations of dissolved VOCs found in the groundwater at the site (Geraghty & Miller
1995).
Between September and November 1993, an IRM was implemented to remove “soil-borne”
contaminants from the concrete sump beneath the floor of the former one-story building,
which is believed to have held VOC-containing liquids (Applied Environmental 1993). In
October 1994, the Phase III excavation and removal of VOC contaminated soils was
implemented at the sump. Approximately 14 cubic yards of soil was removed from the sump
and in November 1994, the sump was backfilled with clean fill and all associated sump piping

was properly sealed (Levco Woodwork Joint Venture 2002). Attachment 3 shows a
schematic of sump excavation and closure sample locations (Geraghty & Miller 1995).
In November 1994, a supplemental site investigation (SSI) was conducted following the IRM.
Three soil borings were drilled (and subsequently converted into monitoring wells) and were
analyzed for VOCs and specific metals. The SSI concluded that the hazardous waste had
been identified and removed from the site and that the remaining contamination in the soil
above and beneath the groundwater table will not adversely affect public health and the
environment due to the lack of environmental receptors in the vicinity of the site (Levco
Woodwork Joint Venture 2002). Following the SSI, a Record of Decision (ROD) was
released stating “no further action” for soil and monitoring of the groundwater on the site for
18 months on a semiannual basis. The site was subsequently deactivated from the Registry
(ID: 2-41-009; NYSDEC 1996).
The following table contains a summary of detected concentrations of VOCs and metals at
the sump from the SSI (Geraghty & Miller 1995):

To meet New York City commercial use criteria, additional remediation at the site is
required. The NYSDEC approved a Remedial Action Work Plan (RAWP) in August 2010
that includes soil excavation to depths ranging from between 4 to 10 feet bgs. Additionally,
the RAWP includes monitoring of residual groundwater contamination to ensure the natural
attenuation of COPCs at the site will ultimately meet NYSDEC standards. Potential
exposures to occupants from soil vapor intrusion (SVI) in the new building (proposed in
2010) will be mitigated via installation of a vapor barrier and ventilated subsurface parking
garage. Institutional controls (i.e., environmental easement) will be implemented to restrict
the use of groundwater for use as potable water without necessary treatment (NYSDEC
2010). These additional groundwater and air monitoring requirements are described further
in Sections 9.2 and 9.5.
9.1.2
Soil Vapor Investigations
In 2003, a RAP was implemented to evaluate soil and groundwater contaminant
concentrations at the site. Based on the results of the remedial alternative evaluation, an
AS/SVE was selected as the remedy to remove VOCs from soil and groundwater at the site.
In June 2003, a soil gas survey was conducted at the site at approximate 50-foot intervals
along the perimeter of the site. TCA was detected in ten samples from 76 micrograms per
cubic meter (µg/m3) to 8,700 µg/m3. TCE was also detected in the ten samples, ranging from
25 µg/m3 to 31,000 µg/m3. Tetrachloroethene was detected in nine samples at concentrations
ranging from 8.1 µg/m3 to 4,300 µg/m3 (Gannett Fleming 2006).
In 2006, a soil vapor investigation was conducted to supplement existing soil and
groundwater data from 2003. The results of the investigation indicated that the presence of
aromatic hydrocarbons, halogenated, and non-halogenated compounds present in the soil
vapor samples suggest an off-site unidentified source contributing to VOC concentrations in
soil vapor. COPCs, including tetrachloroethene, TCE, and TCA were not detected in a
majority of the samples, with the highest total concentration of tetrachloroethene found in
the vicinity of the groundwater plume downgradient of the site (Gannett Fleming 2006).
In 2010, during the development of the RAWP for the planned redevelopment of the site, a
SVI investigation was included. Dvirka and Bartilucci Consulting Engineers (D&B)
completed the SVI at the site in 2010 (D&B 2010). Based on the results of this investigation,
Newtown Creek RI/FS
11
Mayy 2012
120782-01.01
NYSDEC concluded that all potential SVI pathways on- and off-site have been evaluated and
no further sampling or action is warranted related to SVI (Cozzy 2010). The RAWP remedy
decision states that potential exposures to occupants from soil vapor intrusion in the new
building will be mitigated via installation of a vapor barrier and ventilated subsurface
parking garage. In August 2010, NYSDEC approved the RAWP stating the selected remedy
is protective of human health and the environment and complies with state requirements
(NYSDEC 2010). Attachment 11 shows the soil vapor study sample locations.
9.1.3
Soil Summary
COPCs, including chlorinated VOCs and metals, were present in site subsurface soil samples
at concentrations greater than NYSDEC regulatory limits. Several remedial activities have
been performed including the 1991 building decommissioning and excavation, the 1993
IRM, and the 1994 Phase III investigation and excavation in 1994. Recent plans for
redevelopment at the site triggered NYSDEC requirements to excavate residual VOC
contaminated sediments from the site to meet New York City commercial use criteria.
Proposed excavation activities would range between 4 to 10 feet bgs (NYSDEC 2010).

Groundwater Investigations
Several groundwater investigations have been conducted on-site between 1987 and 2010.
In 1987, three monitoring wells were installed as part of a subsurface investigation. Elevated
levels of TCE (1,100 µg/l) were found in groundwater at the site. Subsequent groundwater
samples collected between 1987 and 1989 indicated elevated levels of TCE, TCA, DCE, and
DCA above NYSDEC Division Guidance Values in groundwater. A Phase II Investigation
was conducted at the site per a Consent Order from NYSDEC in 1992 to test and monitor
soils and groundwater at the site. Samples of groundwater at the site indicated exceedances
in VOCs, chromium, and lead. The VOC plume was documented to extend from the
Newtown Creek RI/FS
12
Mayy 2012

northeast portion of the site downgradient to the southwest. Wells in the hydraulically
upgradient area at the northeast portion of the site were not impacted by VOCs from the site.
The investigation revealed the source of the VOC plume to be the main sump inside the
building. The source of VOC contamination was believed to originate from past discharges
of liquid chemicals and waste into the sump (Levco Woodwork Joint Venture 2002). An
IRM was implemented in 1993 to remove impacted material from the sump (Levco
Woodwork Joint Venture 2002).
In 1994, a SSI was conducted following remediation of the sump area. Three soil borings
were analyzed and converted into monitoring wells. Several monitoring wells were analyzed
for VOCs and total and dissolved metals. VOC concentrations exceeding NYSDEC Guidance
Values were documented to be relatively shallow in the water table. Metals exceeding
NYSDEC Guidance Values at the sump were not determined to be a contaminant of concern
in the groundwater both on and offsite because dissolved metals were isolated in the vicinity
of the former sump only. Following the SSI, NYSDEC agreed that no further on- or off-site
investigation was warranted and that monitoring for natural attenuation of VOCs in the
water table was required (Levco Woodwork Joint Venture 2002). Attachment 8 and
Attachments 9 and 10 show concentrations of metals and VOCs in groundwater from 1994
and 1995 investigations.
Subsequent monitoring occurred at the site on a semi-annual basis, beginning in 1996 and
are ongoing at the site. In 2002, a Remedial Action Plan (RAP) was implemented in order to
evaluate residual VOCs in the groundwater at the site. It was concluded that natural
attenuation was limited due to insufficient biological activity and the low dispersive
characteristics of site hydrogeology (Levco Woodwork Joint Venture 2002). In 2002, the site
was registered under a Voluntary Cleanup Agreement (VCA; Voluntary Cleanup Program
[VCP] No. V00600) with NYSDEC to address remaining contamination of groundwater
(NYSDEC 2010a).
In 2003, an AS/SVE was installed at the site as part of the RAP as the selected remedy to
remove VOCs from soil and groundwater. In 2005, the AS/SVE was still operating and
performance monitoring indicated that VOCs were being removed from groundwater, soil,
and soil vapor beneath the site (Gannett Fleming 2006).

In 2008, a Remedial Action Status Report indicated that exceedances for TCE were present in
4 of the monitoring wells (MW-103, MW-341S, MW-350, and MW-403) and exceedances
for cis-1,2-dichloroethene and Tetrachloroethene were present in MW-350, above NYSDEC
Guidance Values (Gannett Fleming 2008). The groundwater plume is limited to the central
portion of the site between 36th and 37th Street as shown in Attachment 10 (NYSDEC 1995).
Groundwater flows southeast in toward East River, which is approximately 1.1 miles from
the site.

dichloroethene, and Tetrachloroethene are still present in the groundwater at the site at
concentrations exceeding NYSDEC Guidance Values (Gannett Fleming 2008). Groundwater
at the site flows southwest to the East River, which is approximately 1.1 miles away.
Therefore, groundwater is not a complete transport pathway to Newtown Creek.

deemed ineffective and was discontinued (Cozzy 2010). Section 10.3 contains more
information regarding the air remediation history for the site.
10 REMEDIATION HISTORY (INTERIM REMEDIAL MEASURES AND OTHER
CLEANUPS)
10.1 Soil Cleanup
Between September and November 1993, an IRM was implemented to remove contaminated
soil from the concrete sump at the site. In October 1994, a Phase III excavation was
conducted removing approximately 14 cubic yards of contaminated soil. In November 1994,
the sump was backfilled with clean fill and all associated sump piping was properly sealed
(Levco Woodwork Joint Venture 2002). In May 1996, the site was de-listed from the
Registry in response to the conclusion of the IRM and investigation activities.
In August 2010, NYSDEC approved a RAWP stating the selected remedy is protective of
human health and the environment and complies with state requirements (NYSDEC 2010).
As part of this remedy, some soil excavation would occur above the water table (between 4
and 10 feet bgs) and residual groundwater contamination will be monitored to ensure the
natural attenuation of COPCs at the site, until NYSDEC standards are achieved (NYSDEC
2010). The remedy also includes the installation of vapor barrier in new building and
construction of ventilated parking garage. Institutional controls (i.e., environmental
easement) will also be implemented as part of the remedy to restrict the use of groundwater
for use as potable water without necessary treatment (NYSDEC 2010).
10.2 Vadose Soil Cleanup
An AS/SVE system installed on the site in 2003 to address elevated levels of VOCs found in
vadose soil at the site (Gannett Fleming 2006). Based on data from the AS/SVE, the system
was expanded along the perimeter of the site, adding two wells to address levels of VOCs
found in soil vapor along the western boundary of the site (Gannett Fleming 2006). These
SVE were placed in locations such as to capture the VOCs in the soil vapor and control their
migration into adjacent structures or beneath the adjacent street (Gannett Fleming 2006). In
2010, the AS/SVE system was deemed ineffective and was discontinued (Cozzy 2010).

10.3 Groundwater Cleanup
During the Phase II investigation at the site in 1992, soils near the sump appeared to be the
source of observed impacts to groundwater at the site (Levco Woodwork Joint Venture
2002). An IRM was implemented in 1993 and Phase II excavation in 1994 to remediate
impacted soils at the sump (as described in Sections 9.2 and 10.1).
The 2008 Remedial Action Status Report showed exceedances for VOCs, including TCE, cis1,2-dichloroethene, and Tetrachloroethene, in groundwater at concentrations above the
NYSDEC Guidance Values of 5.0 µg/L. Groundwater samples were analyzed for VOC via the
U.S. Environmental Protection Agency (USEPA) method 8260 (Gannett Fleming 2008).
10.4 Other Cleanup
The former one-story brick building on the site was decommissioned in 1991. The building
was constructed on a slab of concrete except for a 500 square foot basement at the
northwestern end of the building. The basement included a boiler and AST used to store fuel
oil. Approximately 36,288 gallons of hazardous waste liquids, 38 lab-packs of small
containers holding hazardous waste (less than one gallon each), and 90 cubic yards of
hazardous waste solids (i.e., woodchips, wood and debris) were all removed at this time. The
equipment and interior components were also removed and disposed of at an off-site facility
(Levco Woodwork Joint Venture 2002).

NOTES:
1. Outfall Labeling: BB: Bowery Bay; NC(B/Q): Newtown Creek, Brooklyn/Queens; ST: Stormwater.
2. Outfall locations are preliminary, compiled, estimated data based on New York City Department of
Environmental Protection (NYCDEP) maps and tabulated data and other resources. Many outfall locations
were taken from the New York City Shoreline Survey Program: Newtown Creek Water Pollution Control Plant
Drainage Area, NYCDEP, March 31, 2003. Other locations were taken from an excerpt from a similar report
from 2008 (the complete report was not included in files available for review). Finally, some outfall locations
were inherited from previous Anchor QEA and Newtown Creek Project work. Latitudinal and longitudinal data
provided in the 2003 and 2008 NYCDEP reports were rounded to the nearest second. This resulted in
potential outfall location discrepancies of up to approximately 200 feet. All outfall locations are currently
under field verification.
